Megastructures. What is really the point? - The article explores megastructures in relation to their impact on local transport networks and nodes. The area examined is Portugal, where the recent construction of giant shopping malls, industrial estates and logistics centres has in turn led to large-scale infrastructures that have been superimposed on a settlement pattern consisting, in many cases, of urban agglomerations serviced by rural roads. The resulting landscape reveals a juxtaposition of completely different elements in terms of both scale and impact, often the outcome of urban zoning projects intruding on fragmented urbanisation. The resulting image is one of scattered settlement patterns. Behind these phenomena one can see the effects of splintering urbanism. The difficulty in coordinating, in time and space, the decisions made and actions taken by a wide variety of individuals and institutions is becoming increasingly more complex.
